structures of mine and similar cars, cars, the end structures -comprisingbumpers or buffers and coupling means. l This applicationrelates particularly to end structures compris-- ing bumpers or buffers and three inter-related couplinglinks, the bumpers orA buffers being .15 formed relative to use of those links.

' The object of the-invention `is to adapt the bumpers to make room for the middle link when adjacent cars are moved.y relativelytowardeach other to make theopposing bumpers to bear upon eachother. 'In the accompanying drawings,- y

Referring to the drawings, A, A are side sills. 'In the form shown by the drawings,

, these sills are of channel-shapeeach having 40 an upper lflange, A1, and lailower flange, A2,

both .flanges being directedoutward.

B is the steel plate member of the end sill structures. This has the uprightweb, B1',

lower horizontal flange, B3.y The corners `of the'flange, B2, are cut to make slanting edges,

B4, and the corners of the lower flange, B8, are similarlycut to make slanting edges, B4.-

. (Fig. 1).

5 ,Withthismemben B, are combinedvther WV. Sanford.,V

. and an upper horizontal flange, B2, and a v serial No. 511,412:

members to` form the complete end sill struc-` turein a general way as described insaid Pat.-

' ent, No. 1,486,547, butl with materialdierences, aswillappear further on herein.

In the form shown in the drawings, the plate member, B, is long enough tol partial-1y` -f over-lap the Vadjacenten'ds of the-side sills, Our improvement is applicablev to the end` A: Said'plate'member and the sidev sills arev joined to each other'by means of corner angle members, C, which are unitary castings suchk as are described in said Patent, No. 1,486,547; One armorjblade, Cl, of each vanglemember rests against the outer flat face of the upright-'web ofthe adjacent'fside sill, A, and is secured to saidv web by'rivets, A3, extending through 4said arms and said'webf. The drawings showv sin such rivets.`V The yotheri arm or blade, G2, of each angle member lies4 against the adjacent part ofthe back face, of

the upright web, Bl, of the plate member, BL

Rivets, C3, extend through said arm and saidl web ,to join saidk parts' to eachother. In the drawings, 'sixsuch rivets are shown.

Eachv end sill structure is `a duplicate, lin reverse, ofithe other, it being understood thatsucha structure isfplaced on each 'end 'of' each c ar, so that'when two carsy are coupled to eachother, a pair of such end' structures willbe opposite eachother and may meet when either car is Vmoved/toward the other. Referring to either end structure, an inner or secondmember, D," of strong wood, prefera-` bly oak, is placed on the lower lange,-B3, and` against the upright web, B1', of the plate meniber, B, yThe upper and the lower and the inner faces of thiswood member, D,-are straight; While the outer face of the wood `member conforms approximately to the outer edgeso'f the plate member, B. Its height is less than the ill height of the upright web, Bl, of the plate member, B. Thus space is left between the wood member, D, and the upper flange, B2, of the plate member, that space being sullicient to receive one of the end coupling links, F10.

A metal bumper member, E, is placed on the filling or cushion member, D, atthe middle of the latter. rlfhe member, E, is curved l`and channel-form, having an upright web, El, and an upper flange, E2, and a lower flange, E3. lTheupright web, El, and the upper flange, E2, have an indentation, E4, at the meeting of said web and said liange, said indentation being inclined and conforming approximately to the indentation, Dl, in the cushion member, D'. Thus all of the web, El, bears against the outer face of the cushion member, D. A partk of the lower flange, E3, underlaps the ange, B3, of thev plate member, B.

F our rivets or bolts, D2, are shown eX-V tending through the upper flange, B2, andA the cushion member, D, and the lower flange, B3. Between the upper flange, B2, and the cushion member a spacing sleeve, D3, sur-- rounds each bolt to maintain the distance between said flange and the cushion member.

V`A reinforcing plate, G, is placed onand riveted to the middley part of the upper flange, B2. A shaft form uprightcouplin pin, G-l, extends loosely through the plate, Y upperoflange, B2, and the adjacent end link, F10, andthe upper flange, E2, and the cushion member, D, and the lower members, B3 and E3.

` Aj Each of the end links, F10, normally lies right plane and is shown shorter than the end links, F10-preferably onlyl long enough to couple the longer end links. The end links' are made long enough, and the space between the coupling pins, G l, and the upright web, B1, of the plate member, B, is suflicient to allow' each of said end links, F10, to slide endwise toward the adjacent web, B1, when the two opposing end structures are driven toward or against each other. j

. When force is applied to either car which serves to separate the cars and put the three links under tension, the long links, F10, F10, are held in the horizontal plane which is parallel to and a li'ttle above the upper faces of the flanges, E2, of the bumper member, and the short middle link is suspended between the upper parts of the metal bumper member, E, and substantially out of the indentations, E4. j j

When those `cars approach each other to eliminate the tension on the three links, the lower part of the short, middle, upright link, F9, will be partially/'surrounded bythe faces in the indentations, E4, while the end links,

' F10, are allowed to remain in said horizontal and the` plane and continue to be slidable on the upper flanges, E2, of the bumper. The indentations, E4, are preferably so formed as to ,allow the link, F '9, to seat in the indentations,

forced upward above the upper faces, E2,

of the bumpers, whereby the adjacent ends of lthe long links, F10, would be carried upward, those links then being tilted out of thev horizontalr position.

As `above indicated, when the bumpers meet, the end links, F10, F10, are still in the horizontal position and resting on the upper flanges, E2, of the bumpers and their sliding has no t been arrested by contact with the upright webs, B1. At the same time, the middle link, F9, is seated in the indentations, E4, in ,such manner as to avoid exerting downward force on the adjacent ends of the links, F10, F10, and tending to tilt the links, F1o, F1o. f Y

' Here we note the function attained by eX- tending the indentations, E4, only partially downward along the upright faces of the bumpers. If these indentations were extended further down, the above described seating and supporting of the middle link, F9, would not take place. On the contrary, the weight of the middle link would be supported on the adjacent ends of the long links. ghat would avoid stability of the links, F10,

It is to be understood that the steel plate members, B, are described herein as one means for supporting the metal bumper members, E, and the coupling pins, G1. It is also to be understood that the wood member, D, is preferable, but not essential, as a member of the combination.

. For another form of car to which our improvement is applicable, reference is made tovUnited States Patent N o. 1,562,794, granted to Hugh W. Sanford, November 24, 1925.

We claim as our invention:

l. A horizontal metal bumper for a mine or similar rail car, said bumper comprising an upright wall and said bumper also comprising an upper flange directed toward the car body and the bumper having at the middle upright longitudinal plane of the car anv indentation formed by indenting the upper part of said wall and the adjacent part of said flange, the depth of the indentation belngonly as much as is needed to receive the lower part of one end ofv a horizontal coupling link resting in an upright plane, whereby the lower portion of said wall is uninterrupted.

2. -The combination of a horizontal metal Cit bumper for a mine or similar rail car, said bumper comprising an upright wall and said bumper also comprising an upper flange di rected toward the car body and the bumper having at the middle upright longitudinal plane of the car an indentation formed by indenting the upper part of said wall and the adjacent part of said flange, the depth of the indentation being only as much as isv needed to receive the lower part of one end of a horizontal couplin@r linli; resting in an upright plane, whereby the lower portion of said wall is uninterrupted, and a filler mem=` ber having an outer face conforming to the inner upright face of the .bumper member and the iller member having an up r face conforming to the lower face of t Ae hori zontal flange of the bumper and the'filler member having an indentation adapted to receive the indented part of the bumper.

3. In a railway car of the kind described, a

metal bumper having an upright member and a horizontal upper `member directed toward the car body and said bumper having an upper indentation at the meeting of the upright member and the horizontal member and midway between the ends of said bumper, and means for'supporting a coupling member adjacent said indentation whereby apart of said coupling member which is below the top of said horizontal member ma occupy a portion of said indentation w en said bumper and a similar bumper of an adjacent car meet.

In testimony whereof we havesigned our names, this 24th day of January, in the year one thousand nine hundred and thirty-one.
